Application filed May 14, 1913. Serial No. 767,608.

To all 'LU/wm it may concern Be it known that I, JOSEPH E. COCHRAN, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Apparatus for Use in Manufacturing Gas, of which the following is a specification.

This invention relates to improvements in apparatus for use in manufacturing industrial and commercial gas, and which apparat-us embodies a condenser, a scrubber and a purifier, through which the gaseous fluid is successively passed, out of contact with outside moisture to condense, scrub and purify the gas, and one of the objects of the invention is to provide an improved apparatus of this class having a maximum cooling surface over which the fluid passes for effectively reducing the temperature of the fluid.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement of the severalparts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention and in which- Figure 1 is a top plan View partly broken away, with parts removed and partly in section of an improved apparatus of this class constructed in accordance with the principles of this invent-ion. Fig. 2 is a longitudinal sectional view taken on line 2-2, F ig. 1. Fig. ES is a sectional view taken on line 3--3, Fig. 2.

Referring more particularly to the drawings and in the present exemplification of this invention, the numeral 10 designates generally a closed casing having an inlet 11 for the gaseous fluid and an outlet 12. The easing or chamber .10 is divided by means of a plurality of hollow partitions 13, 14 and 15 into a plurality of compartments designated generally by the reference numerals 16, 17, 18, 19, and the partitions may be so arranged that the compartments may be of any desired relative size.

The compartment 16 constitutes a condensing chamber and within this compartment a plurality of hollow baille members 20 are arranged, that extend from the top to the bottom of the compartment, and from opposite sides thereof. The respective baffles terminate short of the opposite side of shown more clearly in F ig. 2, so that the gaseous fluid which enters the compartment 16, through the inlet 11 will flow -in a tortuous path through the compartment and wlll at the same time flow across and contact with the faces of the baffles. The baffles are also so arranged with respect to each other, that the passage between the adjacent baffles gradually decreases in size as it approaches the passage between the end of the baffle and the compartment wall, to reduce the stream of fluid as it flows over the baffles.

Leading from the compartment 16, preferably at points adjacent the top thereof are a plurality of outlet pipes 22 which extend into the vnext'adjacent compartment 17 and terminate adjacent the bottom of the compartment. Similar tubes 23 extend from points adjacent the top of the compartment 17 and project int-o the compartment 18, terminating at points adjacent the bottom of the latter. These tubular members 22, 23, form the inlets for Huid in the compartments 17 and 18, and the outlet for the fluid from the compartments 16 and 17. In the present form of this invention the compartments 17 and 18 constitute scrubbers and embody reticulated or perforated supports 24 arranged in the respective compartments and upon which supports masses of impurity removing agents, such as coke are arranged, and the supports 24 are so positioned that the extremities of the tubes or pipes 22, 23y will project therebelow. Y l/Vith this arrangement, the fluid entering the compartments 17, 18 will be discharged thereinto, below the respective impurity removing agent 25 and will flow through such agents on its passage out of the respective chambers.

Leading from the compartment 18 are tubular members 26 similar to the tubular members 22, 23, from points adjacent the top of the compartment 18 and extend into the compartment 19 and terminate short of the bottom thereof, for conducting the fluid from the compartment 18 into the compartment 19. Arranged in this compartment 19 is an apertured support 27 dividing the compartment into two other compartments one above the other. ln the loivermost compartment is arranged an impurity extracting agent or mass 2S such as semi-liquid lime and arranged above the support 27 is another impurity removing agent 29 such as eolie, lime, saw-dust or any suitable material and through both of which agents 2S, 29, the fluid passes on its Way out of the compartment 19 through the outlet 12.

Leading from the bottom of the compartment 1G are a series or outlets 30 which are connected with a manifold 31 in which latter may be arranged a controlling valve 32. Similar outlets lead from the compartments 17 and 18 and are connected with a manifold. Se in which may be arranged a controlling valve 35.

The hollow partitions and the hollow baffies 2O have communication with the outside air and any means may be provided for inducing circulation of a cooling medium therethrough. ln the present exemplification of this invention a series of inlets 36 are connected Vith the partitions and baffles, for the admission olf the cooling medium and series of flues 3T are also connected With the respective battles and partitions for inducing the circulation. It desired, a fan, not shown, may be provided for assisting in inducing this circulation.

lilith this improved construction, the gaseous fluid from the time that it is generated and enters the inlet 11, dees not come in contact, or commingle with any outside moisture, during its entire passage through the apparatus, thereby preserving all of the valuable properties of the fluid, which would be soluble to moisture, and which would be lost or carried away vvith the moisture should the latter commingle with the gas.

During the passage of the fluid through the compartment 1G it flo-Ws in a tortuous path formed by the baflles 2O and condensation takes place in this compartment caused by the cooling surfaces of the baffles through which the temperature reducing medium is circulating. F rom the compartment 1G it passes by means or' the pipes 22 into the scrubber 17 so as to pass through the impurity removing agent 15 to enter the pipes 23 to be conveyed thereby into the compartment 1S so that it will pass, through the impurity extracting agent 25 therein. During its passage through these compartments 17 and 18 it is maintained out of commingling relation with the temperature reducing medium circulating in the hollow partitions and also out of contact with outside moisture. From the compartment 18 the fluid passes by means of the pipes 2G in the lovcer chamber in the compartment 19 to be discharged into the impurity removing agent 28 in which latter the ends of the pipes 26 are submerged. T his agent 28 is moist When placed in the apparatus and after being once installed is maintained out ot contact With outside moisture during the entire time the fluid is passing through the apparatus. From this lowermost chamber` the fluid passes through the support 27 and the impurity removing agent 29 in the uppermost chamber of the compartment, and from thence through the outlet 12 to the point of consumption or storage. The heavier than gas particles Which have been deposited in the respective chambers may be removed through the outlet pipes 30, Obviously man-holes 3G may be provided wherever de sired, so that ready access may be had to the respective compartments.

While in the present exemplification of this invention, the preferred forms of construction and arrangements of the several parts have been shown and described, it is to be understood that various changes maj7 be made in the details of construction, and combination and arrangement oit' the several parts Without departing from the spirit of this invention.
